| Zusammenfassung | Thz technology has proven a valuable tool both in fundamental research and practical applications, including diagnostics, measurements and testing. Well-known advantages include the ease of use of non-ionizing radiation, a better spatial resolution than radio waves, and the possibility of performing non-contact measurements in optically opaque dielectric materials like foams, adhesives, glass fiber mats or plastics and composites. THz imaging and thickness profilometry enable the inspection of non-conducting compound materials, including surface varnishing or foam coatings of thermal insulators. In particular, time-domain spectroscopy (THz-TDS) has become widely used in science and, increasingly, also in industrial applications for nondestructive testing in either reflection (R) or transmission (T). However, a recent international intercomparison of TDS transmission measurements, which involved 18 academic and industrial participants, demonstrated a high variability of measurement outcomes from a set of identical samples. Moreover, measurements in reflection geometry are even more challenging, but are mandatory in many industrial settings. For both R+T measurements, a certified reference material is highly desirable. The development of such an artifact is the goal of a joint R&D project of PTB and TOPTICA. |
